Book Description
The application of elastic theory to the design of overlays on existing pavement requires that a modulus of elasticity be assigned to the existing structural system. Estimates of elastic modulus are obtained from dynamic deflection reading in the field; but asphalt is a highly temperature-sensitive visco-elastic material and deflections not corrected to a standard temperature can produce misleading results. It is therefore the objective of the present study to develop a procedure for estimating an effective modulus of elasticity for a layer of asphaltic concrete in which some temperature gradient exists because of the combined influences of solar radiation, wind, air temperature, cloud cover and other variables specific to time and location which cause temperature variation within the pavement layer. Two models are presented from the achievement of that objective.

Temperature Predictions and Adjustment Factors for Asphalt Pavement
Author: Erland O. LukanenPublisher:
ISBN:
Category : Pavements, Asphalt
Languages : en
Pages : 86
Book Description
This report presents the results of an analysis of the response that deflections and backcalculated asphalt moduli have to the pavement temperature. The study used deflection and temperature data from 40 sites monitored in the Seasonal Monitoring Program of the Long Term Pavement Performance (LTPP) program. The report presents improved methods of estimating the temperature within an asphalt pavement based on the measurement procedures used for the LTPP program. The data necessary to estimate the temperature within the asphalt included the surface temperature, time of day, depth below the surface, and the average air temperature from the previous day.
